MACHINE FOR MlLLl N G DROP-BOXES FOR LOOMS.

SPECIFICATION formingpart of Letters Patent No. 229,115, dated June 22, 1880. Application filed February 9, 1880.

To all whom it may concern Be it known that we, MERRILL A. FUR BUSH, a citizen of the United States, residing in Philadelphia,Pennsylvania, and BENJAMIN F. MEYER, a citizen of the United States, residing in Oamden,New Jersey, have invented an Improvement in Machines for Milling Drop- Boxes for Looms, of which the following is a specification.

he object of our invention is to accurately and rapidly plane the bottoms and backs of the several compartments of drop-boxes for looms; and this object we attain by the mechanism too fully described hereinafter to need preliminary explanation.

In the accompanying drawings, Figure 1, Sheet 1, is a perspective view of our machine for planing the drop-boxes of looms; Fig. 2, a perspective view of a drop-box; Fig. 3, Sheet 2, a vertical section on the line 1 2, Fig. 1; Fig. 4, a vertical section on the line 3 4, Fig. 1; and Fig. 5, an inverted perspective view of one of the arms for carrying a rotaryniillingtool and gearing for operating the same.

The base A of the machine has longitudinal V-shaped grooves adapted to similarly-shaped longitudinal ribs 0, a on the under side of the table or bed B. It has not been deemed necessary to illustrate or describe mechanism for 0 moving the table on the base, as this may be accomplished by a screw or by properly-com structed gearing, in conjunction, if desired, with automatic devices, such, for instance, as are used in operating the tool-carrying slides of metal-planing machines.

The drop-box on which the machine is designed to operate, and which is best observed in Fig.2, consists of a back plate, d, a number of horizontal ribs, 1) b I), 850., and a front plate, f, all being cast in one piece, the box being thus separated into a number of compartments, into any one of which the shuttle may be received after its flight, as the posi tion of the box may determine. It is impor- 5 tant that the bottom and back of each compartment of the box should be true in order to form proper bearings for the shuttle, and it is the accurate planing of these parts for which the machine is intended.

To opposite sides of the base are secured the standards E E, to which is attached the cross-frame F, the latter and the standards being similar to those of an ordinary metalplaning machine.

0n the frame F are longitudinal beveled guides for the horizontal adjustable plate G,

which has twosimilar guides for the two plates H H, the plate H having vertical guides e 6, adapted to the carriage K, and the plate H similar guides adapted to the carriage K. Each of these carriages is under the'control of a screw-shaft, M, which can turn in but is confined vertically to a projection on the plate H or H, the threaded portion of the shaft being adapted to a nut on the back of the carriage.

The plate G may be adjusted by hand on the guides b b of the cross-frame F, suitable provision being made for securing the plate after adjustment; or the said plate may becontrolled by a screw or suitable gearing.

Each of the plates H H, with its carriage, must admit of being separately adjusted on the guides of the plate G, and thisadjustment may be effected by hand or by screws or other devices.

A vertical shaft, P, has its bearings in projections on the carriage K, and to the lower end of this shaft is secured a cog-wheel, h, which is contained within a longitudinal slot in a horizontal arm, m, projecting from and forming part of the carriage, and the wheel h is geared through intermediate wheels with the wheel I on a spindle which carries the milling-disk i, on the horizontal face of which are teeth for milling or planing the backs of the compartments in the shuttle-box.

The shaft 1? passes through and can slide in a worm-wheel, n, the hub of which is confined vertically to but can turn freely in a projection on the plate H, the shaft being grooved for receiving a feather in the wheel, the latter gearing into a worm, la, on the shaft- N, which has its bearings on brackets attached to the frame of the machine. The worm is confined between projections on the plate H, so as to move with the latter, and has afeather adapted to a longitudinal groove in the shaft N, so that, whatever may be the position of the plate or carriage, the milling-disk will be revolved from the shaft N, and the carriage can be raised or lowered without stopping this shaft and the milling-disk.

The carriage K carries a vertical shaft, P, which is driven from the shaft N by a worm and wheel, in a manner similar to that described above.

A bevel-wheel, p, on the lower end of the shaft P, gears into a bevel-wheel, g, on a spindle which carries a wheel geared through a train of intermediate wheels with a wheel which carries the milling-tool it, having teeth on its vertical face for planing the bottoms of the compartments of the drop-box, the train of wheels being contained within a vertical slot in the arm m, which projects from the carriage K.

The drop-box D having been placed with its rear face downward on the bed B of the machine, and then secured by suitable fastenin gs, the carriages K K are so adjusted in respect to each other by moving the plates H H on the sliding plate G that the milling-disk on the arm of the carriage K will plane the back of one compartment of the drop-box while the milling-disk of the carriage K planes the bottom of the adjoining compartment, the bed of the machine being fed as the planing is continued.

After the bed of the machine has been moved back so as to clear the arms m m of the carriages K K, the sliding plates G may be so adjusted on the cross-frame F, and the carriages thereby moved together to such a position, that the milling-tools will act on the backs and bottoms of the other compartments of the drop-box until the whole of the compartments have been properly planed, the pro- 0 jecting arms of the two carriages permitting the milling-tools to act beneath the plate f of the drop-box.

We claim as our invention- 1. A planing or milling machine in which a reciprocating bed, B, carrying the object to be planed, and a carriage, K, adjustable on the frame of the machine and having an arm, m, parallel with the bed B, and carrying a milling-disk, are combined with gearing, substantially as described, through which the said disk may be rotated from a shaft adapted to bearings on the frame, all substantially as set forth.

2. In a planing or milling machine, the bed B, for carrying the object to be planed, two independen tly-adj ustable carriages, KK, each having an arm carrying near its outer end a milling-tool, the cutting-face of one tool being at right angles to that of the other, in combination with gearing, substantially as described, whereby both cutters may be operated simultaneously from a shaft adapted to fixed bearings on the frame of the machine, all substantially as set forth.

3. The combination of the carriage K, its arm m, the wheel I on the spindle which carries the milling-disk i, the shaft P, and the train of gear-wheels by which the milling-disk is driven from the said shaft, all substantially as specified.

4. The combination of the cross-frame F, the plate G, adjustable thereon, the plates H H, separately adjustable on the plate G, the carriages K K, adjustable on the plates H H, the shafts P P, and gearing, substantially as described, whereby the said shafts may be rotated from the shaft N, as set forth.

In testimony whereof we have. signed our names to this specification in the presence of two subscribing witnesses.
